Exchanges Of Carbon And Nitrogen Between Tidal Freshwater Wetlands And Adjacent Tributaries : A Final Report, Iris C. Anderson, Scott C. Neubauer, Betty B. Neikirk, Richard L. Wetzel

Reports

Tidal freshwater marshes are hypothesized to export materials and energy that support primary and secondary production in estuaries, yet there are few data available to test this hypothesis. A major objective of our study was to measure net exchange of carbon between marsh and atmosphere to determine whether biogenic carbon inputs are in excess of those required to produce observed biomass, satisfy the measured accretion rate, and keep pace with the historical rate of sea level rise. To determine whether the marsh exports materials and energy we measured exchanges of nutrients between marsh sediments and overlying water and of nutrients, …
